I've passed the AWS Certified Cloud Practitioner the 19th of October with 884/1000. The exam was more tricky than expected. Although I read everywhere the AWS exams are always more tricky as you expect. I can confirm that reading the whitepapers is very important. The Linux Academy course provides a really good foundation on understanding the concepts and learning some important services but it does not cover everything. You should really know every service which is mentioned in the whitepapers.
Thanks Linx Academy! Now I start with AWS Solutions Architect Associate!
